Basic instructions - Important notice regarding equipment servicing
AXIAL-FLOW® 5140 NA
AXIAL-FLOW® 6140 NA
AXIAL-FLOW® 7140 NA
All repair and maintenance work listed in this manual must be carried out only by qualified dealership personnel,
strictly complying with the instructions given, and using, whenever possible, the special tools.
Anyone who performs repair and maintenance operations without complying with the procedures provided herein
shall be responsible for any subsequent damages.
The manufacturer and all the organizations of its distribution chain, including - without limitation - national, regional, or
local dealers, reject any responsibility for damages caused by parts and/or components not approved by the manu-
facturer, including those used for the servicing or repair of the product manufactured or marketed by the manufacturer.
In any case, no warranty is given or attributed on the product manufactured or marketed by the manufacturer in case
of damages caused by parts and/or components not approved by the manufacturer.
The information in this manual is up-to-date at the date of the publication. It is the policy of the manufacturer for
continuous improvement. Some information could not be updated due to modifications of a technical or commercial
type, or changes to the laws and regulations of different countries.
In case of questions, refer to your CASE IH Sales and Service Networks.

Safety rules - Ecology and the environment
AXIAL-FLOW® 5140 NA
AXIAL-FLOW® 6140 NA
AXIAL-FLOW® 7140 NA
Soil, air, and water quality is important for all industries and life in general. When legislation does not yet rule the
treatment of some of the substances that advanced technology requires, sound judgment should govern the use and
disposal of products of a chemical and petrochemical nature.
Familiarize yourself with the relative legislation applicable to your country, and make sure that you understand this
legislation. Where no legislation exists, obtain information from suppliers of oils, filters, batteries, fuels, anti-freeze,
cleaning agents, etc., with regard to the effect of these substances on man and nature and how to safely store, use,
and dispose of these substances.
Helpful hints
• Avoid the use of cans or other inappropriate pressurized fuel delivery systems to fill tanks. Such delivery systems
may cause considerable spillage.
• In general, avoid skin contact with all fuels, oils, acids, solvents, etc. Most of these products contain substances
that may be harmful to your health.
• Modern oils contain additives. Do not burn contaminated fuels and or waste oils in ordinary heating systems.
• Avoid spillage when you drain fluids such as used engine coolant mixtures, engine oil, hydraulic fluid, brake fluid,
etc. Do not mix drained brake fluids or fuels with lubricants. Store all drained fluids safely until you can dispose of
the fluids in a proper way that complies with all local legislation and available resources.
• Do not allow coolant mixtures to get into the soil. Collect and dispose of coolant mixtures properly.
• The air-conditioning system contains gases that should not be released into the atmosphere. Consult an air-condi-
tioning specialist or use a special extractor to recharge the system properly.
• Repair any leaks or defects in the engine cooling system or hydraulic system immediately.
• Do not increase the pressure in a pressurized circuit as this may lead to a component failure.
• Protect hoses during welding. Penetrating weld splatter may burn a hole or weaken hoses, allowing the loss of oils,
coolant, etc.
Battery recycling
Batteries and electric accumulators contain several substances that can have a harmful
effect on the environment if the batteries are not properly recycled after use. Improper
disposal of batteries can contaminate the soil, groundwater, and waterways. CASE IH
strongly recommends that you return all used batteries to a CASE IH dealer, who will
dispose of the used batteries or recycle the used batteries properly. In some countries,
this is a legal requirement.
Mandatory battery recycling
NOTE: The following requirements are mandatory in Brazil.
Batteries are made of lead plates and a sulfuric acid solution. Because batteries contain heavy metals such as lead,
CONAMA Resolution 401/2008 requires you to return all used batteries to the battery dealer when you replace any
batteries. Do not dispose of batteries in your household garbage.
Points of sale are obliged to:
• Accept the return of your used batteries
• Store the returned batteries in a suitable location
• Send the returned batteries to the battery manufacturer for recycling

10. INTRODUCTION
Safety rules - Personal safety
AXIAL-FLOW® 5140 NA
AXIAL-FLOW® 6140 NA
AXIAL-FLOW® 7140 NA
Carefully study these precautions, and those included in the external attachment operators
manual, and insist that they be followed by those working with and for you.
1. Thoroughly read and understand this manual and the attachment Operator’s Manual before operating this or any
other equipment.
2. Be sure all people and pets are clear of the machine before starting. Sound the horn, if equipped, three times
before starting engine.
3. Only the operator should be on the machine when in operation. Never allow anyone to climb on to the machine
while it is in motion. If the machine is equipped with an Instructors Seat, this must only be used for training
purposes. Passengers must not be allowed to use the Instructors Seat.
4. Keep all shields in place. Never work around the machine or any of the attachments while wearing loose clothing
that might catch on moving parts.
5. Observe the following precautions whenever lubricating the machine or making adjustments.
• Disengage all clutching levers or switches.
• Lower the attachment, if equipped, to the ground or raise the attachment completely and engage the cylinder
safety locks. Completing these actions will prevent the attachment from lowering unexpectedly.
• Engage the parking brake.
• Shut off the engine and remove the key.
• Wait for all machine movement to stop before leaving the operators platform.
6. Always keep the machine in gear while travelling downhill.
7. The machine should always be equipped with sufficient front or rear axle weight for safe operation.
8. Under some field conditions, more weight may be required at the front or rear axle for adequate stability. This is
especially important when operating in hilly conditions or/when using heavy attachments.
9. Always lower the attachment, shut off the engine, set the parking brake, engage the transmission gears, remove
the key and wait for all machine movement to stop before leaving the operators platform.
10. If the attachment or machine should become obstructed or plugged; set the parking brake, shut off the engine
and remove the key, engage the transmission gears, wait for all machine or attachment motion to come to a stop,
before leaving the operators platform to removing the obstruction or plug.
11. Never disconnect or make any adjustments to the hydraulic system unless the machine and/or the attachment is
lowered to the ground or the safety lock(s) is in the engaged position.
12. Use of the flashing lights is highly recommended when operating on a public road.
13. When transporting on a road or highway, use accessory lights and devices for adequate warning to the opera-
tors of other vehicles. In this regard, check local government regulations. Various safety lights and devices are
available from your CASE IH dealer.
14. Practice safety 365 days a year.
15. Keep all your equipment in safe operating condition.
16. Keep all guards and safety devices in place.
17. Always set the parking brake, shut off the engine and remove the key, engage the transmission gears, wait for all
machine or attachment motion to come to a stop, before leaving the operators platform to service the machine
and attachment.
18. Remember: A careful operator is the best insurance against an accident.
19. Extreme care should be taken in keeping hands and clothing away from moving parts.
